I Can't download 2.7 for OS X

[Ryno]

I am having the same problem. In my case, I tried downloading the 
installer for Dreamcard (several times) from this page: 
http://downloads.runrev.com/dreamcard/ ... The installer downloads OK, 
but then, on expanding, the following message appears:

> An error has occurred while expanding the file 
> "install_download.app.sit" (The archive may contain damaged content). 
> Error #17538

This is particularly worrying as I only bought Dreamcard one month ago, 
and the last thing I want is to be obsolete so quickly, particularly if 
Dreamcard is going to be dropped.

Incidentally, I received the following email offer from Runrev:

> Hurry - this special offer ends on Monday 27th February! Get your copy 
> of the new Revolution 2.7, or upgrade your existing copy - and we'll 
> give you the wonderful Constellation free - a saving of $50. Just make 
> any purchase over $199 to qualify.

This message came up in "Mail" without images, so I cannot figure out 
what is meant by this offer. If it applies to me, and I hope it does 
one month after purchase(!), I cannot act on it because the download 
does not work. To make things worse, of course, the offer expires in 
two days...

Ryno.
